WATCH PENDANT.

Application lled July 29, 1925. Seriall No. 46,849.

This invention aims to provide a dustproof pendant for a watch, and soto construct the device that an. accidental setting of the watch will beavoided. Other objects will be made manifest as the descriptionproceeds.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings Figure 1 shows in section, a device constructe'd inaccordance with the invention, parts being in elevation; Figure 2 is atop plan; Figure 3 is a plan showing a screw driver which may be used inconnection with the device shown in Figures 1, 2 and 4; Figure 4 is asectional elevation showing a slight modification.

The numeral 1 marks a watch having a pendant 2. A stem 3 is journaled inthe pendant 2 and has a transverse shoulder 4 located within the pendant2, the shoulder being adapted to cooperate with a flange 5 on the outerend of the pendant. The stem 3 is threaded at 6 into the bore 7 of acrown 8 having a recess 9 receiving the outer en'd of the pendant 2. Acompressible washer l0, made of leather or any other suitable material,is seated in the recess 9 of the crown 8 and bears on the outer end ofthe pendant 2. The stem 3 extends through the washer 10. A bow 11 isconnected at 12 to the pendant 2 for swinging movement in a well knownway. The bow 11 has an in wardly extended projection 14 which isprolonged almost into engagement with .the crown 8. A retainer 15, suchas a screw, is threaded into the bow 11 and the projection 14 and entersthe bore 7 or the crown 8, the screw 15 being provided at its inner endwith a concaved seat 16 adapted to receive the rounded end 17 of thestem 3. The screw 15 has a longitudinal slot 19 extended inwardly fromthe outer end of the screw, and extended entirely thrcaigh the screwfrom side to side. Into the outer end of the slot 19 may be inserted ascrew driver 20, which may be used as a watch charm.

In Figure 4 of the drawings, parts hereinbeifore described have beendesignated by numerals previously used with the suiiix m. Themodification consists in forming an outward projection 21 on the bow 11aand mounting a cap 22 removably on the projection 21, the cap 22 housingthe end of the screw 15a.

The device requires no adjustment what ever for winding, since the crown8 can rotate on the inner end of the screw 15, that portion of the screwwhich extends into the bore 7 of the crown being smooth. In order to setthe watch, the screw 1.5 is backed out a little, and the bow 11 is swungover to one side. Then, the stem 3 may be pulled outwardly into settingposition, by means of the crown 8, the shoulder 4 on the stem 3 engagingthe flange 5 of the pendant 2. The bow 11 is yieldable enough sothatwhen the screw 15 is advanced into engagement with the stem 3, as shownin Figure 1, the stern and the crown 8 will be carried inwardly, therebycompressing the washer 10, so that the washer will bethoroughlyeifective to exclude dust. As a matter of fact, not merely a dust-proofjoint, but a water-proof joint is formed. The setting of the watchcannot be. changed accidentally by` hand, because the screw 15 holdsdown the stem 3. The rotary bearing between the screw 15 and the stern 3can be oiled by the user of the watch, it being unnecessary to do anywatchmakers work in order to effect such an oiling. The article callsyfor no adjustment of parts, se far as the winding of the watch isconcerned, since the winding may be brought about, as hereinbeforeexplained, when the device is arranged as shown in Figure 1. The stem 3may be adjusted longitudinally by substituting for one washer, anotherwasher of a dierent thickness. The ends of the bow 11 will not wearloose readily, because the bow does not have much swinging movement, itbeing necessary to swing the bow only when the watch is to be set.

The slot 19 in the screw 15 has two purposes: iirst, it may be used inthreading the screw 15 in or out: secondly, the slot may be openedslightly, when the screw is detached, thereby spreading the screw andcausing the screw to take up wear, when it is again threaded into place.

Tfhat is claimed is l. In a Watch comprising a pendant, a stem in thependant, al Crown carrying the stein, a Washer in the crown andcooperating' with the end of the pendant, and a boW mounted vforswinging movement; an improvement Which consists of a combined means forholdingthe bow against swinging movement, for holding` the stem againstaccidental setting` movement, and for compressing the Washer, said meansen'ibodying a member held in the bo\v for adjustment at the will ot anoperator and entering the crown'and engaging the stem.

2. A, device of the class described, constructed as setl Yforth in claiml, and further characterized by the fact that said member is accessiblethrough the outermost portion of the bow for adjustment at the will otan operator.

3. A device of the class described, constructed as set forth in claim l,and further characterized by the tact that said member is in the form ofa screw, threaded into the outermost portion of the bow and having ascrew-driver slot accessible through said portion of the bonv and deepenough, measured longitudinally of the screw, to permitan expansion ofthe screw to take up Wear therein.

In testimony that I claim the foregoing as my own, I have hereto aiiiedmy signature.
